Usetyenziso

I-TETREDM ingasetyenziselwa njenge-solvent egqwesileyo ye-alkaline metal hydride kwaye isetyenziswe kwindibaniselwano ye-alkyl okanye i-recycle reaction reaction. NgoLouise Alkalinity, inokukhetha ngokukhetha irhasi yeasidi ukucoca igesi yokwenziwa, igesi yendalo kunye neacetylene. (QAPHELA: le mveliso ayinakuvezwa ngaphandle ixesha elide, kungenjalo inokuvelisa iperoxide.)

Ukupakisha

200kg / igubu; 1000kg/IBC

Ukugcinwa kufuneka kube kwindawo epholileyo, yomile kwaye ivule umoya.
